Claims.

This invention relates to improvements in refrigerating apparatus and more especially to such apparatus of the portable type particularly adapted for domestic use. i

Among the features of our invention is the combination of a shelf type evaporator adapted to support ice trays with a transverse guide member adjacent the front edge of the shelf and a carriage slidably mounted on the guide member, said carriage being provided with ice tray release mechanism.

Another feature of the invention is the provision of an apron in front of the evaporator shelf, said apron carrying the guide member above mentioned. This apron is preferably made removable to facilitate cleaning and repair. The apron may also support a thermometer.

Another feature of the invention is a vertical removable plate mounted above and in front of the evaporator shelf, in front of the ice trays to conceal the same from view when the door is open, and provide better cooling of the ice trays. Means are provided for swinging this plate upwardly and backwardly to a horizontal position to permit removal of the ice trays from the evaporator shelf and under the plate.

Other features and advantages will appear more fully as we proceed with our specification.

In that form of device embodying the features of our invention shown in the accompanying drawingsFig. 1 is a view in front elevation of the food compartment of a refrigerator; Fig. 2 is a similar view on an enlarged scale of the upper portion thereof; Fig. 3 is a view taken as indicated by the line 3 of Fig. 2; Fig. 4 is a view taken as indicated by the line I of Fig. 2; Fig. 5 is a vertical sectional view taken through the evaporator shelf and the baiiles underneath taken on the line 5 of Fig. 6; Fig. 6 is a view taken as indicated by the line 6 of Fig. 5; Fig. 7 is a fragmentary View similar, to Fig. 2 taken on an enlarged scale; and Fig. 8 is a view taken as indicated by the line 8 of Fig. 7.

As shown in the drawings, l0 indicates the food compartment of a refrigerator which may be of any conventional type adapted for mechanical cooling. indicate the usual shelves in the compartment for supporting food.

In the refrigerating apparatus here shown we use a shelf type of evaporator which may be, for example, similar to the evaporator shown in Figs. 10, 11, 12, and 13 of Touborg and Rosebrook Patent 2,009,910 issued July 30th, 1935. Since the details of the construction and operation, of such an evaporator are fully disclosed in that 1937, Serial No. 158,601

patent it is unnecessary that they be repeated here.

The evaporator in general in the form of a flat shelf we have indicated by the reference numeral l2 and the cooling boilers thereunder by the reference numerals Hi. We shall use the numeral I2 to indicate the evaporator in general, it being understood that in the practice of this invention we employ any evaporator of the shelf type, that is, any evaporator including a sub stantially flat imperforate shelf. One of the features of this invention is to make the shelf substantially the same size and shape as a horizontal cross-section of the food chamber In and locate said shelf near the top of the chamber so that there will be a small compartment Illa. above the shelf for theaccommodation of ice trays ll.

In front of the evaporator, across the front of the foodcompartment, there is provided a removable apron 2|, the ends of which are bent at right angles as indicated by 22 and provided with holes 23, 23 to receive the pins 24, 24 in the walls of the food compartment. Springs 25, 25 serves to center the apron on the pins and permit removal of the same from the refrigerator by pressing the same to one side against the compression of one of the springs until the pins on the other side are released.

26 indicates a thermometer carried on the rear side of the apron 2| and visible through a slot 21 therein.

Carried betweent'he ends 22, 22 of the apron 2| is a guide member 28 having a carriage 29 slidably mounted thereon, said carriage having rotatably mounted in its upper end the blade member 30 provided with the handle 3|. The

blade 3|] can be rotated in the carriage and also slid backwardly or forwardly. The guide member 28 extends across the front of the refrigerator just back of the apron 2|. With this construction, the blade can be moved in front of any ice tray and the flattened end 30a thereon pushed under the curved front edge of the ice tray and the blade rotated to release the ice tray from the shelf I2. (See Fig. 8.)

The upper edges of the apron 2| are bent backwardly to form narrow horizontal flanges 2la and 2|b at the upper and lower edges of the apron 2|.

32 indicates a vertical removable plate mounted above and in front of the shelf 2 in front of the ice trays. Means are provided for swinging this plate upwardly and backwardly to a horizontal permit removal of the ice trays from the shelf the position shown in solid lines to that shown The plate 32 is also removable in broken lines. from the box. It isshort enough so that it can be pushed to one side against the tension of one of the springs 35 until the pins from the other ends are released from the slots when the plate can be taken out bodily.

As another feature of the invention we have also shown. the mounting of the thermostat 5la on the back of the apron 2|, said thermostat being controlled by the usual knob 5| in cooperation with the dial 50. The wires 52 indicate the usual connections of the thermostat to the rest of the refrigerating apparatus, the details of which need not be shown.

While we have shown and described certain embodiments of our invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is our intention to claim all novelty inherent in our invention as broadly as permissible, in view of the prior art.

What we claim as new, and desire to secure by Letters Patent, is:

' ice tray release mechanism carried by said carriage.

2. In refrigerating apparatus, in combination 7 with a shelf type evaporator adapted to support ice trays thereon, a vertical plate mounted above and in front of the shelf in front of the ice trays,

and means for swinging said plate upwardly and backwardly to a horizontal position to permit removal of ice trays from said shelf and under said plate.

3. Apparatus as claimed in claim 2 in which the plate is bodily removable from the refrigerating apparatus.

4. Refrigerating apparatus, including: a shelf type evaporator; a transverse apron adjacent the front edge of the shelf, the ends of said apron being bent backwardly at right angles; a transverse guide member carried by said backwardly bent ends of the apron, a carriage slidably mounted on said guide member; and ice tray release mechanism carried by said carriage.

5. Refrigerating apparatus, including: a shelf type evaporator; a transverse apron adjacent the front edge of the shelf; a transverse guide member mounted on said apron, a carriage slidably mounted on said guide member and ice tray release mechanism carried by said carriage.
